Definitions
- the present invention falls within the technical field of the manufacture of ceramic tiles. More specifically, the present invention relates to the process and to the compositions employed in the decoration of the tiles after their manufacture. STATE OF THE PRIOR ART OF THE INVENTION
- the manufacturing process of ceramic tiles can include successive firings at high temperatures that permanently consolidate the inks and coatings applied on their surface, by forming a glass.
- the application of inks and coatings is done by many different procedures, including screen printing, gravure, flexography, spraying, curtain, brushwork, etc.
- the composition of the inks and coatings used includes the pigments suitable to achieve the desired chromatic characteristics and the vitrifiable material that allows its consolidation when subjected to cooking.
- new inks are applied on the tile, annealing again at a slightly lower temperature.
- This succession of cooking is energetically expensive, both in the cost of operation and in the necessary investment.
- numerous pigments cannot be used, so the decorative possibilities are limited.
- radiation curable compositions (ES 2 147 066 Al)
- the present invention relates to ceramic tiles decorated with radiation-curable inks and coatings, the process of application and consolidation of said materials, and the compositions employed therein.
- ceramic tiles includes those pieces that, made of ceramics, are used to cover floors and walls, regardless of their shape, size or that are covered with an enamel of an ayoritarian vitreous nature.
- the decorative process consists of a first stage of application of the ink or coating. The procedure can be any of those existing in the industry (silkscreen, gravure, flexography, curtain, spray, pad printing, manual painting, etc.). The tile must be clean and dry.
- the decorative process consists of a second stage, whose objective is the consolidation of the ink or coating on the tile, which consists in the application of ultraviolet radiation of the appropriate intensity so that the system completely crosslinks.
- the two previous steps can be repeated successively, if it is desired to use several inks or coatings, up to a maximum of 10 times.
- Prior to the previous decoration process it is possible to subject the tile to various processes that maximize adhesion between the substrate and the layers of ink or coating that are deposited on it and, as a consequence, allow to improve the properties of the coatings .
- a first alternative is to subject the tile to a sandblasting process.
- said silane is a compound capable of creating Si-O-Si bonds on the surface of the ceramic tile.
- This third process can be used in isolation or in combination with any of the previous two.
- the compositions used can employ both a free radical crosslinking system and a cationic system. In turn, they can be loaded with a colorless inorganic material, which improves the mechanical and / or chemical properties of the coating, and / or with a pigment, which gives it its chromatic characteristics.
- compositions based on a free radical polymerization mechanism comprise the following materials: - Oligomer: 20-90% - Mono: 20-90% - Photoinitiator: 0.5-4% - Adhesion promoter: 0-4% - Additives: 0-3%
- the oligomer used is one or more organic compounds belonging to any of the following families: epoxy, polyester, polyurethanes, acrylic or that includes the corresponding functional groups in addition to the functional group reactive to radiation, which may be the acrylate, methacrylate or vinyl function.
- the prepoly ero will be selected from a diacrylate polyester, a triacrylate polyester, a dimethacrylate polyester, a trimethacrylate polyester, a diacrylate polyether, a triacrylate polyether, a dimethacrylate polyether, a polyether trimethacrylate, a polyester polyether, a polyester polyester polyether triacrylate, a polyester polyether dimethacrylate, a polyester polyether trimethacrylate, an aliphatic polyurethane, a polymer liurethane diacrylate, a polyurethane triacrylate, a polyurethane dimethacrylate, a polyurethane trimethacrylate, a polyester polyurethane diacrylate, a polyester polyurethane triacrylate, a polyester polyurethane dimethacrylate acrylate acrylate acrylate , an acrylic triacrylate, an acrylic trimethacrylate.
- the monomer is one or more organic compounds containing reactive mono- or poly-functional groups of the acrylate or methacrylate type.
- the photoinitiator will be composed of any substance capable of generating free radicals with adequate energy to initiate the reaction when subjected to ultraviolet radiation.
- said initiator system is constituted by: (i) a derivative of a thioxanthone substitution, (ii) an amino derivative, (iii) derivative of acetophenone, combined in any proportion and without necessarily all three being present.
- the photoinitiator mixture to be used will depend fundamentally on whether it is a transparent coating or the type of pigment used.
- the adhesion promoter is an organic compound, which contains at least one silanol group, capable of forming Si-O-Si bonds with the vitreous surface on which it comes into contact. In the case of multiple applications, this compound is only necessary in the application of ink or lower coating, in contact with the ceramic tile.
- the additives used are those materials that, used in individual proportions of 0-1% but less than 1%, are not actively involved in the crosslinking process. These additives include stabilizers against aging and against effect of sunlight, rheology and surface tension modifiers, viscosity modifiers, wetting or removal of bubbles, dispersants, wetting agents or deflocculants, etc.
- compositions based on a cationic cross-linking mechanism comprise the following materials: - Oligomer: 60-90% - Polyol: 0-40% - Photoinitiator: 1-4% - Adhesion promoter: 0-4% - Additives: 0-3%
- the oligomer is any type of resin, containing reactive epoxy or vinyl groups.
- epoxy resin usable in these compositions are cycloaliphatic epoxy resins, glycidyl ethers and epoxidized oils.
- vinyl ethers and urethane-type vinyl ether resins are also usable.
- the polyol which provides toughness and flexibility to the cured compositions, is one or more polyols selectable between a polyester polyol, a polycaprolactone polyol, a polyether polyol, a polyacrylate polyol, a polyvinyl polyol, a polyol of polycarbonate and the like.
- the photoinitiator is one or more compounds, capable of initiating the reaction when subjected to ultraviolet radiation, such as diazonium salts, halonium salts, sulfonium salts, triarylselenonium salts, sulfoxonium salts or some organometallic complexes.
- the adhesion promoter is an organic compound, which contains at least one silanol group, capable of forming Si-O-Si bonds with the vitreous surface on which it comes into contact. In the case of multiple applications, this compound is only necessary in the application of ink or lower coating, in contact with the Ceramic tile.
- an inorganic material (0-50%) that acts as a load and that considerably increases the mechanical properties. If this material is of high particle size, the transparency of the coating is severely affected; however, if a material of sufficiently small particle size is used, a transparent coating with optimal mechanical properties can be obtained.
- these compositions can be mixed with any type of pigment (0-50%) to obtain the desired color characteristics.

- the application of the inks has been done by phonography, gravure and screen printing.
- the coatings have been applied by curtain. After applying the inks and coatings, they were cured by application of a source of UV radiation, with an intensity of 160 W / cm and at a speed of 15 m / min.
- the oligomer mixture used in Examples 1-4 consists of two acrylated aliphatic polyurethanes of different molecular weight and with different number of acrylate functions.
- a difunctional monomer (DPGDA) has been used. The proportions of both oligomers and the monomer have been selected in order to optimize the mechanical and chemical properties of the coating, as well as its viscosity and its adhesion to the substrate.
- the silane used has provided an acceptable support adhesion, superior to scratch resistance of the coating, so it has not been a problem. It is also possible to use other silanes, if other resins are used in the coating.
- the photoinitiator system has provided a good cure, both superficial and deep. In examples 1 and 2, corresponding to transparent coatings, the photoinitiator system has been a mixture of ⁇ -hydroxy ketone and ⁇ -amino ketone, while in the colored inks it has been changed to a mixture of indroxyketone and bis-acyl-phosphine (BAPO ), in order to obtain both superficial and deep curing.
